Abstract

The invention discloses a cooperative description method for an internal type component and an attribute component composition structure of an ecological system, and relates to the cooperative description method for the internal type component and the attribute component composition structure of the ecological system. The invention aims to solve the technical problem that the internal compositionstructure condition of the ecosystem is difficult to comprehensively display by the existing method. The method comprises the following steps: generating attribute raster data of internal type components of the ecological system; and constructing frequency distribution of attribute components of the internal type of the ecosystem. According to the method, the composition structures of the type components and the attribute components in the ecosystem are organically combined, so that the advantages of the two composition structure description methods are integrated, the defects of the single composition structure description methods are overcome, and the description method for comprehensively reflecting the internal composition structure of the ecosystem is formed. The method belongs to thefield of ecosystem attribute structure description.

Description

technical field [0001] The invention relates to a collaborative description method for the internal type and attribute composition structure of an ecosystem. Background technique [0002] The strength and quality of ecosystem functions depend on the quality of its internal structure, so a comprehensive and systematic description of the internal structure of the ecosystem, especially the compositional structure, is very necessary. In the past, when assessing the internal composition and structure of the ecosystem, the description method of the type component structure was usually used, that is, based on the classification of the internal components of the ecosystem, the distribution area or the proportion of the area occupied by the type components The histogram of the ecosystem is used to express the composition structure of the type components within the ecosystem; however, the above method cannot reflect the variation of the attributes within each subtype component of the ...
